\(n_{CO2}=0,14\left(mol\right),n_{Ca\left(OH\right)2}=0,08\left(mol\right)\)
\(1< \frac{n_{OH^-}}{n_{CO2}}< 2\rightarrow\) Tạo CaCO3; Ca(HCO3)2
Dặt nCaCO3=x; nCa(HCO3)2=y
\(\left\{{}\begin{matrix}2x+y=0,14\\x+y=0,08\end{matrix}\right.\rightarrow\left\{{}\begin{matrix}x=0,06\\y=0,02\end{matrix}\right.\)
\(m_{kt}=0,06.100=6\left(g\right)\)
Trong dd có Ca(HCO3)2
\(\rightarrow CM_{Ca\left(HCO3\right)2}=\frac{0,02}{0,8}=0,025M\)
